We'll describe our new audio run-time and toolset that was built specifically for Killzone Shadow Fall on PlayStation 4. However, the ideas used are widely applicable and the focus is on integration with the game engine and fast iteration, with special attention to shortcuts to get your creative spark translated into in-game sounds as quickly as possible. We will demonstrate our implementation of these demands, which is a next-gen sound system that was designed to combine artistic freedom with high run-time performance. It should be interesting to both creative as well as technical minds who are looking for inspiration on what to expect from a modern sound design environment. To emphasize the performance advantage, we will show the point of view of both the sound designer and the programmer simultaneously. We will use examples starting with simple sounds and build up to increasingly more complex dynamic ones to illustrate the benefits of this unique approach.
